Abstract

PURPOSE:To enhance a visual confirmation capacity and prevent the accumulation of snow by intertwining a plurality of strands and adding filling wires having color and a reflective surface to intertwining grooves. CONSTITUTION:The application of filling wires 4 largely reduces conventional large-sized intertwining grooves 3, which prevents snow accumulated on the grooves, thereby reducing the adherence of snow due to the grooves 3. Then, filling plastic wires are used as the wires 4 where they are built-up in the shape of a fan of fan substantially similar to the shape of the grooves 3 in the cross section and provided with a flattened portion on the outside surfaces coated with fluorescent paint or the like. Since they are colored with a multi-color fluorescent paint or the like, the visual field is enhanced so that they may be more easily visualized. In this case, the intertwined grooves are more remarkably reduced while the reflection of light is more enhanced. This construction make it possible to prevent snow from being deposited thereon and allow guard ropes to be seen constantly and hence prevent the generation of hazards as well.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guard rope installed on a highway, a mountain road or the like to prevent danger.

[0002]

2. Description of the Related Art Conventionally, as this kind of guard rope, as shown in the sectional view of FIG. 3, a rope formed by twisting three or more strands 1 of galvanized steel is used. ing. And this twisted wire is usually constructed by combining seven galvanized steel wires 2.

[0003]

As a matter of course, the guard rope is required to be well visible in the field of view and have a high strength for the purpose of its installation. However, in areas with a lot of snow, there is a problem that a large amount of snow adheres to the guard rope and the purpose cannot be sufficiently achieved.

That is, the snow starts to accumulate on the portion of the twist groove 3 of the guard rope and is gradually connected to this to increase the adhesion, and almost all the circumference is covered.

Therefore, the guard rope is melted into the snow scene on one side and is not visible in the visual field. Also, due to the weight of adhesion,
May cause looseness.

[0006] In addition, the light reflection of the guard rope at night is extremely weak and difficult to see regardless of whether or not snow adheres.

[0007]

DISCLOSURE OF THE INVENTION The present invention is intended to solve the above problems and deficiencies. The first feature of the present invention is to allow a filler wire to be fitted more into the groove of the guard rope so as to prevent snow from being generated by the groove. It is intended to reduce the adhesion.

A second feature is that the filling wire is colored so that the guard rope can be seen well not only in the daytime but also at night.

The third feature is that the filling wire is more easily added, and the material and shape are modified so that the effects of snow removal and light reflection can be easily obtained. The details will be described below with reference to the illustrated embodiment.

[0010]

【Example】

Example 1: FIG. 1 shows a cross-sectional view of a guard rope in Example 1, and a partial cross section of a strand 1 of galvanized steel is omitted. In FIG. 1, reference numeral 1 denotes a strand of galvanized steel obtained by twisting seven galvanized steel wires 2 having a diameter of 2.85 mm at a pitch of 114 mm, and twisting three twisted wires at a pitch of 180 mm. In this structure, three twisted grooves 3 are formed. In order to reduce the groove, the galvanized steel wire 4 having a diameter of 4.0 mm was added to each groove to obtain a guard rope R.

Example 2 An orange fluorescent paint was applied to the outer surface of the filling wire 4 shown in FIG. 1 to prepare a colored guard rope.

Example 3: As shown in FIG. 2, as the filling wire, a filling plastic wire 4'having a fan-shaped cross section similar to the shape of the groove 3 and having a flat surface 5 on the outer surface was used. The outer surface of the wire was coated with a fluorescent paint for light reflection.

[0013]

As apparent from the comparison between the embodiment shown in FIGS. 1 and 2 and the conventional example shown in FIG. 3, in the present invention, the conventional large groove 3 is greatly reduced by the filling wires 4, 4 '. Therefore, the adhesion of snow due to the groove is reduced, and the problem due to snow is solved.

In the second embodiment, since the outer surface of the filling wire is colored, it is easy to be seen in the field of view and the effect of preventing danger is improved. Since the outer surface of this filling wire is circular and diffusely reflects light and weakens the reflected light, it is preferable to use a fluorescent paint that is self-luminous for coloring.

In the third embodiment, since the filling wire is made of plastic, it is easier to put it together, and since the outer surface is fan-shaped and the outer surface is flat, the groove is further reduced and the reflection of light is good. Fluorescent paints that are not luminous are also sufficient.

In the above-mentioned embodiments, all three twist grooves are filled with the filling wire, but depending on the installation location, one wire may be sufficient, and one color may be applied. May be sufficient.

The material of the filling wire is not necessarily limited to the galvanized steel wire and the plastic wire, and can be selected depending on the place of use and manufacturing problems.

For the same reason, the shape of the filling wire can be selected such that a round wire and a fan shape are used together, and the shape of the guard rope is also based on the outer diameter obtained by twisting the strand 1 of the basic steel. It is also possible to make one of the outer surfaces of the filling wire more prominent so as to protrude so that the snowfall on the guard rope can slide off well.

[0019]

EFFECTS OF THE INVENTION Since the present invention is constructed as described above, the location of the guard rope can always be clearly seen, the role of preventing danger can be sufficiently fulfilled, and obstacles due to snow adhesion can be reduced.
